Full-Year Consolidated Data files (released annually in November) – The main person-level file of the Household Component data set, which includes all demographic and medical characteristics, as well as patient-reported responses to the main survey questions. Since the survey involves five interview rounds over the two-year panel, data from interview rounds 1, 2, and 3 are included for individuals in their first of two years, and data from interview rounds 3, 4, and 5 are included for individuals in their second of two years. These single-year consolidated datafiles can be thought of as the first half of one two-year panel survey stacked on top of the second half of another two-year panel survey. The Full-Year Population Characteristics files (released annually in May) – A skeleton version of the person-level consolidated file, which gets released six months before the Consolidated file of the same year but does not include any income or medical expenditure variables. The Medical Conditions files (released annually in November) – The medical condition-level file, which can be linked to both the person-level files and the event-level files. Unlike the medical event-level files, which describe a solitary encounter with the U.S. healthcare system, records within the Medical Conditions files contain a distinct ICD-9 code, Clinical Classification Code, and describe only one ailment (illness or injury). In order to view all medical events during the calendar year associated with a particular condition, a many-to-one join can be executed between this file and zero, one, or more of the event-level files' records (on CONDIDX). The medical condition records in this file can also be merged with a many-to-one join to the person-level files (on DUPERSID), where each person may have zero, one, or multiple matching condition records. The Jobs files (released annually in May) – The jobs-level data file contains information about each job that each MEPS-HC survey respondent held over the course of the calendar year, including wages, hours, industry, and occupation, as well as various healthcare-related survey questions (such as offers of employer-sponsored insurance, sick day availability, etc.). This file can be merged with the full-year *person-level file (on DUPERSID), with one match per unique job an individual held during the calendar year. It can also be merged with the Person Round Plan file, matching (on JOBSIDX) wherever a private health insurance plan was obtained through a place of employment.
